- MACHINE FOR SHAPING .ME'TAL BY ROLLS.

SPECIFICATION forming part of Letters Patent N6. 627,546, dated. June27,1899.

Application filed March 1 6, l 8 9 9 To all whom zit may concern.-

Be it known that I, JOHN TEDELL, a citizen of the United States,residing at Moline, in. the county of Rock Island and State of Illinois,have invented certain new and useful Improvementsin Machines for ShapingMetal by Rolls; and I do hereby declare the follow;

ing to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to machines for shaping metal parts by rollsoperating to upset portions of the blank and forge the same to conformwith a recessed die, the particular of which is illustrated intheaccompanying drawings, forming part of this specification.

Figure I represents the machine, partly in side elevation and partly insection, with the parts in the relative positions obtaining normally orwhen a blank is first introduced.

Fig. II is a similar View of a portion of the machine with the relationof parts changed, as when the rolls have operated on the blank and upsetportions of the same. Figs. III and IV show sections on different linesof portions of the rolls and the forged blank, the scale beingconsiderably enlarged as compared with Figs. I and 11. Fig. V representsthe machine in front elevation. Fig. VI shows the dieclamping mechanismin rear elevation, together with the lower roll.. Fig. VII representsthe die in perspective. Fig. VIII represents the blankin perspective,and Fig. IX represents the finished product in perspective.

The framework of the machine comprises side standards a of bifurcatedform, which are erected upon a suitable bed-plate, as that of a type ofmachine forgiving reciprocatory motion commonly known as a bulldozer,

the cross head or slide of the same being designated by the letterb. Thebifurcations of the said standards are occupied by two pairs ofjournal-boxes c and d, one pair resting against the bottoms of thebifurcations and the other pair resting upon heavy spiral springse,bearing on the lower pair of journalboxes. The frame is completed by acap f,

which is securely bolted to the side standards,

and screws 9 passithrough bosses provided for them in this'cap-piece,said screws bearing against the upper pair of journal-boxes and beingequipped at their upper ends with hand-wheels 9, whereby the upper pairof journal-boxes are adjusted again st the tension of the springs. Theseupper journal-boxes support a roll h, circular in cross-section andhaving an exterior surface which is convex from end to end. The lowerjournal-boxes support a roll 2', which is partiallycircular incross-section and has a face which is concave from end to end,conforming with the convex-' ity of the roll h, whose convex surface isin close contact with the concave surface of the lower roll. The latterhas formed integrally with it anarm 'i, the lower end of which iscoupled with the cross-head b by a link j, so-

that reciprocations of said cross-head will produce oscillations of theconcave roll to such an extent as to bring the major portion of the faceof the latter into contact with the upper roll. The lower roll is madewith a movable section 7t,- which constitutes a die, said sectionslidingly engaging a cut-out portion of the roll and being concavedinitsouter side in conformity with the balance of the face of the roll.

The machine here shown is designed to operate upon a blank for aplow-land'side, and the die is is made with a shallow recess in (seeFig. VII) in its in nerface','of triangular outline, the two edges ofthe blank not acted on by the rolls being adapted to engage the sides ofthisrecess which are substantially at right angles to the inner face ofthe die-block. This recess opens out of the concave face of the block,and the latter is cut out slightly for a considerable distance from theshort side of the recess, as shown at 10 forming a groove which widensas it approaches the" opposite end of the block, as shown at 70 thelower side of the recess 70 merging into the bottom of the widenedportion of said groove, as shown at k.

The landside-blank is shown in Fig. VIII and designated by the letter m,and it will be observed that the same is generally triangular inoutline, one side, however, having a double curve, giving it a bulgenear the narrow end of the blank, as shown at m. As before stated, thisblank occupies the recess is, and when its two straight sides engage thesides of said recess the curved side stands slightly above the concaveface of the dieblock, so as to provide sufficient metal to be rolleddown into the groove 70 the bulge m of the blank providing sufiicientmetal to fill the widened portion k of the said groove, so

- that when the rolls have operated on the v relation.

blank it will be caused to completely fill the die-recesses and partakeof the shape of the same. 7

Fig. IX represents the product of the machine, and it will be observedthat the curved side of the blank is rolled down, so as to provide abead m extending along the greater portion of its length, and that thebulge m of the blank is rolled down into a thin fiat blade on. Adie-plate n (see Figs. III and IV) is let into the surface of the roll'11 opposite the recess in the die-block, and the blank is clampedbetween this die-plate and said block by the following-describedmechanism. A draw-bolt 0 is fitted to slide through an opening in theroll and engages a registering opening in the die-block, the latteropening, however, being of somewhat less diameter than that in theroll-body and the bolt being shouldered at 0' to bear against the innerface of said block and screw-threaded on its end which projects from theblock, so that a nut 0 applied to said screw-threaded end,may secure theblock to the boltin a fixed A lever 0 is pivoted at its upper end tolugs 0 formed upon the rear side of the roll 1', and said lever isjointed at 0 to the bolt 0 and at its lower end is formed with alongitudinal slot 0 This slot is engaged by a pin 0 fastened in theouter end portion of a bifurcated arm 1), which extends on oppositesides of the lever 0 and is fastened to a stud p, journaled in the arm6. A tumbler-plate p is also fastened to said stud and extends at anangle to the arm 1), said tumbler-plate being of oblong form andbifurcated at its outer end, as shown at 19 A stud or pin p is fastenedin one of the standards a, of the frame and projects from the inner sidethere of for engagement with the bifurcation of the tumbler-plate, saidbifurcation being of a flaring form, so as to enable its sides toreadily engage the said pin or stud.

The normal position of the parts is illustrated in Fig. I, and it willbe observed that the lever o lies in close proximity to the rear side ofthe arm 2', and the tumbler-plate is for the most part in rear of thepin 1%. Upon the forward movement of the arm 1' the upper side of thebifurcation of the tumbler, riding against the pin 19 causes the saidtumbler to turn on its pivot, which results in a corresponding movementof the arm and pressure of the pin 0 against the upper side of the slot0 whereby the lever o is forced outwardly or away from the arm 2", andconsequently draws upon the bolt 0 and forces the die-block 7c inwardly.Before the tumbler leaves the pin 19 it has been turned to the positionshown in Fig. II, where the pin 0 has passed the center or a radius ofthe stud p at right angles to the lever 0 causing the clamping mechanismto lock itself. Upon rearward movement of the arm i the tumbler againencounters the pin 1), so that it will be turned back to its originalposition, releasing the die-block from its clamping adjustment andpermitting the removal of the landside. hen the arm i is driven forward,it will be seen that all portions of the blank projecting from the faceof the concave roller will encounter the convex face of the upper rollerand will be upset thereby into the form shown in Fig. IX, the surface ofthe beaded and flattened portions of the blank partaking of thecurvature of the upper roll, as well illusstrated in Fig. IV. hen thearm t" is returned to its original position, this outer surface of theblank is again acted upon by the upper roller, so that a finishingaction is had, and the landside issues in condition to be welded to theshare.

It will be seen that by interchanging dieblocks the machine can beadapted to the production of various articles, and it is the intentionto employ the machine for upsetting the edge of the share to adapt itfor welding to the landside.

I have here shown a machine especially designed to operate upon blanksfor plow parts; but it is to be understood that a great variety ofotherarticles can be produced by a machine constructed in accordancewith my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-
